Philosophy of Care

As a pediatric gastroenterologist, I enjoy building a partnership with my patients, their families and other members of their health care team in order to work together to improve his or her health over time.

I understand families are often quite worried and overwhelmed by the time they come to see me for evaluation. I strive to provide evidence-based care rooted in the medical literature. I am honored to have the opportunity to guide my patients and their families through the diagnostic and treatment journey.
